[0041] The following will describe in detail the detailed embodiments of the present invention with reference to the accompanying drawings. It should be understood that the detailed embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not used to limit the present invention.

[0042] As a first aspect of the present invention, there is provided a puncture needle unlocking device, wherein, as Figure 1 described, the puncture needle unlocking device 230 includes:

[0043] A clamping body for fixing the puncture needle 270;

[0044] A clamping movable member 232 is provided. The clamping movable member 232 is arranged at one end of the clamping main body and is used to lock or unlock the needle handle of the puncture needle 270.

[0045] An elastic member 233 is provided. The elastic member 233 is arranged inside the clamping main body. One end of the elastic member 233 is connected to the clamping main body, and the other end is connected to the clamping movable member 232, and is used to stretch the clamping movable member 232.

[0046] A button 234 is provided. The button 234 passes through one end of the clamping main body and contacts the clamping movable member 232, and is used to squeeze the clamping movable member 232 when being pressed and push out the puncture needle 270.

[0047] The puncture needle unlocking device provided by the present invention fixes the puncture needle through the clamping main body. The clamping movable member can lock the needle handle of the puncture needle under the stretching action of the elastic member, and can unlock the needle handle of the puncture needle when the button is pressed. Furthermore, the puncture needle is pushed out by the action of the button, realizing the rapid unlocking of the puncture needle. Therefore, the puncture needle unlocking device provided by the present invention has the advantage of being able to quickly replace the puncture needle, and can realize the clamping and manual pressing and pushing out of the puncture needle, with a simple and compact structure.

[0048] It should be noted that as Figure 2 shown, the specific structure of the puncture needle 270 may include a needle tube 271, a needle handle 272, and an infusion tube 273. The needle handle 272 includes a needle handle main body and a round rod portion 2721. The round rod portion 2721 is connected to the needle handle main body. One end of the infusion tube 273 and one end of the round rod portion 2721 on the same side as the first side edge 2722 of the needle handle main body are connected. One end of the needle tube 271 and one end of the round rod portion 2721 on the same side as the second side edge 2723 of the needle handle 272 are connected.

[0049] It should be understood that the puncture needle unlocking device provided by the present invention is not only applicable to Figure 2 the puncture needle structure shown, but can also be used to lock other types of puncture needles.

[0050] Specifically, as Figure 3 shown, the clamping movable member 232 includes a movable member main body portion 2323, a hook portion 2321, and a first inclined surface 2322. The hook portion 2321 is arranged at one end of the movable member main body portion 2323. The first inclined surface 2322 is arranged on the movable member main body portion 2323. The first inclined surface 2322 can contact the button 234. The hook portion 2321 is used to lock or unlock the needle handle 272 of the puncture needle 270.

[0051] It should be noted that the puncture needle unlocking device provided by the present invention may include a clamping movable member or a plurality of clamping movable members, and the plurality of clamping movable members can be linked and locked from multiple directions.

[0052] As a specific embodiment of the button 234, as Figure 4 shown, the button 234 includes a connecting plate 2344, a second inclined surface 2341, a pressing portion 2342 and an ejecting portion 2343. The second inclined surface 2341, the pressing portion 2342 and the ejecting portion 2343 are all arranged on the connecting plate 2344, and the second inclined surface 2341 and the ejecting portion 2343 are arranged on one side of the pressing plate 2344, and the pressing portion 2342 is arranged on the other side of the connecting plate 2344. The second inclined surface 2341 contacts the clamping movable member 232.

[0053] It should be noted that the pressing direction and the ejecting direction of the button in this embodiment are the same. It is also possible to make the pressing direction and the ejecting direction inconsistent by adding a direction conversion structure, etc. Specifically, it can be set according to requirements and will not be elaborated here.

[0054] Specifically, under the action of the elastic member 233, the hook portion 2321 of the clamping movable member 232 locks the second side 2723 of the needle handle 272, and stably fixes the puncture needle 270. At this time, the first inclined surface 2322 of the clamping movable member 232 presses the second inclined surface 2341 of the button 234, and holds the button 234 in the first position (as Figure 5 ), and the pressing portion 2342 of the button 234 is located in the needle handle ejection hole but keeps a distance from the needle handle 272.

[0055] When the puncture needle 270 penetrates into the human body puncture target and needs to be retained, and the puncture needle 270 needs to be separated from the puncture device. At this time, press the pressing portion 2342 of the button 234, and the button 234 moves downward against the elastic force of the elastic member 233. The second inclined surface 2341 of the button 234 presses the first inclined surface 2322 of the clamping movable member 232, and pushes the clamping movable member 232 to slide in the unlocking direction. When the hook portion 2321 of the clamping movable member 232 completely disengages from the needle handle 272, the ejecting portion 2343 of the button 234 begins to contact the needle handle 272 (the second position, as Figure 6 and Figure 7 shown), but there is no pressing force on the needle handle. Continue to press the button 234, and the ejecting portion 2343 applies a pressure to the needle handle 272, and ejects the needle handle 272 from the needle handle receiving groove 2311, as Figure 11 and Figure 12 shown. This facilitates further operations for medical staff.

[0056] It should be understood that in this embodiment, according to the conventional operation habit, the medical staff needs to be located as Figure 13In front of the state shown, the incision direction of the puncture needle needs to be upward, so the needle handle of the puncture needle is located opposite to the medical staff, which is not conducive to the operation of the medical staff. Therefore, after adopting the above implementation method, when the puncture needle is pushed out, the medical staff presses the rear end of the needle handle to smoothly proceed to the next step.

[0057] After the needle handle is successfully unlocked, release the button 234, and under the action of the elastic member 233, the clamping movable member 232 returns to the locked state. The first motor 210 and the second motor 220 return to the initial non-puncture position. When the needle clamping operation is performed again, the operator can directly press the needle handle 272 into the needle handle accommodating groove 2311. During the pressing process, the needle handle 272 squeezes the hook 2321 (the outer edge of the hook 2321 can be chamfered to facilitate installation and squeezing), the elastic member 233 is slightly deformed, and the hook 2321 reaches the second position. At this time, the ejection part 2343 has no force on the needle handle, and the puncture needle 270 can be locked smoothly.

[0058] It should be noted that the first side 2722 of the needle handle 272 is set at a position away from the needle tip, and the second side 2723 is set at a position close to the needle tip. In this way, during the needle insertion process, the force-bearing surface is the fixed first side 2722, ensuring that no deformation occurs during the force-bearing process, thereby improving the puncture accuracy.

[0059] As a specific implementation of the clamping body, Figure 1 As shown, the clamping body includes a clamping fixing seat 231 and a clamping fixing cover 235, the clamping fixing seat 231 is used to accommodate the puncture needle 270, the clamping fixing cover 235 is connected to the clamping fixing seat 231, and one end of the clamping fixing cover 235 is provided with a mounting hole 2351, and the mounting hole 2351 is used to install the button 234.

[0060] More specifically, if Figure 6 and Figure 8 As shown, the clamping fixing seat 231 includes a fixing seat main body and a mounting portion, the mounting portion is arranged at one end of the fixing seat main body, the fixing seat main body is provided with a mounting groove, the mounting groove is used to accommodate the elastic member 233, the mounting portion is provided with a needle handle accommodating groove 2311 and a needle handle ejection hole 2312, the needle handle accommodating groove 2311 is used to fix the needle handle 272 of the puncture needle, and the needle handle ejection hole 2312 is used to accommodate the ejection portion 2343.

[0061] More specifically, if Figure 8As shown, the needle handle receiving groove 2311 includes a round rod portion receiving groove 2311a, a needle handle abutting wall 2311b, and a locking notch 2311c. The round rod portion receiving groove 2311a is used to receive the round rod portion 2721 of the needle handle of the puncture needle, the needle handle abutting wall 2311b is used to fit with the first side 2722 of the needle handle of the puncture needle, and the locking notch 2311c contacts the clamping movable member 232.

[0062] It should be noted that when the puncture needle 270 is in the locked state ( Figure 5 , Figure 9 , Figure 10 ), the needle handle 272 of the puncture needle 270 is placed in the needle handle receiving groove 2311. The round rod portion 2721 of the needle handle 272 fits with the round rod portion receiving groove 2311a, the first side 2722 of the needle handle 272 fits with the needle handle abutting wall 2311b. Under the action of the first elastic body 233, the hook portion 2321 of the clamping movable member 232 locks the second side 2723 of the needle handle 272, and the puncture needle 270 is stably fixed under the action of three directions.

[0063] Preferably, the elastic member 233 includes a spring.

[0064] Therefore, the puncture needle unlocking device provided by the present invention uses manual pressing of the button to determine the pressing speed and distance, which is more user-friendly and convenient to adjust.

[0065] As a second aspect of the present invention, a puncture module is provided. As shown in Figure 13 and Figure 14 , the puncture module 200 includes a first motor 210, a second motor 220, a connecting bracket 240, and the aforementioned puncture needle unlocking device 230. The connecting bracket 240 is respectively connected to the fixed end of the first motor 210 and the output end of the second motor 220. The puncture needle unlocking device 230 is arranged at the output end of the first motor 210. The output end of the first motor 210 can drive the puncture needle unlocking device 230 to perform a reciprocating linear motion along a first direction, and the output end of the second motor 220 can drive the connecting bracket 240 to perform a reciprocating linear motion along a second direction. The puncture needle unlocking device 230 can fix the puncture needle and can eject the puncture needle when being pressed.

[0066] The puncture module provided by the present invention, due to the adoption of the aforementioned puncture needle unlocking device, fixes the puncture needle through the clamping main body. The clamping movable part can lock the needle handle of the puncture needle under the stretching action of the elastic part, and can unlock the needle handle of the puncture needle when the button is pressed. Furthermore, the puncture needle is ejected by the action of the button, realizing the rapid unlocking of the puncture needle. Therefore, the puncture module provided by the present invention has the advantage of being able to quickly replace the puncture needle, and can realize the clamping and manual pressing and ejection of the puncture needle, with a simple and compact structure.

[0067] Further specifically, the first direction is perpendicular to the support plane, and the second direction forms an angle a with the support plane.

[0068] Preferably, the value range of the angle a is 10° to 70°.

[0069] It should be noted that the support plane is Figure 13 As shown, P represents the surface of the human skin. The connecting bracket 240 is fixedly connected to the fixed end of the first motor 210 and the output end of the second motor 220 respectively. The clamping module 230 is fixedly connected to the output end of the first motor 210. The output end of the first motor 210 can drive the clamping module 230 to perform a reciprocating linear motion in the M1 direction. The output end of the second motor 220 can drive the module composed of the connecting bracket 240, the first motor 210, and the clamping module 230 to perform a reciprocating linear motion in the Z2 direction. The Z2 direction is perpendicular to P, the M1 direction forms an angle a with P, and the value range of a is 10° to 70°. The preferred values are 15°, 20°, 30°, 45°, and 60°. Figure 13 As shown, the angle a is 20°.

[0070] It should be understood that the first motor 210 can adjust the puncture depth, and the second motor 220 can realize the needle insertion process. In this way, through the simple combination of the two motors, precise puncture of the puncture target detected by the detection module 110 can be achieved.

[0071] In addition, when the usage purpose is different, the corresponding goal can be achieved by adjusting the stroke of the motor and the value of the angle a.

[0072] It should also be noted that the first motor 210 and the second motor 220 can specifically be linear propulsion motors. Compared with traditional motors, since the output end of the transmission motor is a rotational motion and needs to be converted into a linear motion through a lead screw, etc., the advantage of the linear propulsion motor is that the output end of the motor directly performs a linear propulsion motion, reducing the number of assembly parts and assembly errors.

[0073] To realize the movement of the first motor 210 and the second motor 220, as Figure 13As shown, the puncture module 200 further includes a first slide rail 250 and a second slide rail 260. The second slide rail 260 is disposed on the connection bracket 240 and is used to provide a sliding track for the first motor 210 to perform a reciprocating linear motion in the first direction. The first slide rail 250 is disposed on the probe housing 120 and is used to provide a sliding track for the second motor 220 to perform a reciprocating linear motion in the second direction.

[0074] For the specific implementation manner of the puncture needle unlocking device in the puncture module provided by the present invention, reference may be made to the foregoing description, and details are not described herein again.

[0075] As a third aspect of the present invention, an ultrasonic puncture guiding device is provided, wherein, as Figure 15 shown, the ultrasonic puncture guiding device includes:

[0076] An ultrasonic probe module 100, which can be communicatively connected to the host module 300, is used to detect a puncture target and send the detected ultrasonic signal of the puncture target to the host module 300;

[0077] A puncture control module 500, which can be communicatively connected to the host module 300, is used to form a puncture control signal according to the position information of the puncture target obtained after the host module processes the ultrasonic signal;

[0078] The puncture module 200 described above, the puncture module 200 is electrically connected to the puncture control module 500 and is used to puncture the puncture target according to the puncture control signal.

[0079] For the ultrasonic puncture guiding device provided by the present invention, the ultrasonic probe module detects the puncture target and forms an ultrasonic signal to be sent to the host module. After the host module processes the ultrasonic signal, the position information of the puncture target is extracted and sent to the puncture control module. The puncture control module forms a control signal according to the position information of the puncture target to control the puncture module to automatically puncture the puncture target. Moreover, since the puncture module adopts the foregoing puncture needle unlocking device, the puncture needle is fixed by the clamping main body, the clamping movable part can lock the shank of the puncture needle under the stretching action of the elastic member, and can unlock the shank of the puncture needle when the button is pressed, and then the puncture needle is ejected by the action of the button, realizing the rapid unlocking of the puncture needle. Therefore, the ultrasonic puncture guiding device provided by the present invention can not only accurately identify and locate the puncture target, but also has the advantage of quickly replacing the puncture needle.

[0080] Specifically, as Figure 13As shown, the ultrasonic probe module 100 includes a probe housing 120 and a detection module 110 disposed at one end of the probe housing 120. The detection module 110 can be communicatively connected to the host module 300, and is used to detect a puncture target and send the detected ultrasonic signal of the puncture target to the host module 300.

[0081] Specifically, the ultrasonic puncture guiding device further includes a bracket module 400, and the bracket module 400 is used to support the ultrasonic probe module 100, the puncture control module 500, and the puncture module 200.

[0082] It should be noted that the bracket module 400 realizes the movement of the ultrasonic probe module 100 and the puncture module 200 in the Z1 direction and the Y1 direction by setting a first movable part and a second movable part. For example, when the first movable part slides, it can drive the ultrasonic probe module 100 and the puncture module 200 to move in the Y1 direction, and when the second movable part moves along the axial direction of the first movable part (i.e., the direction perpendicular to the support plane), it can drive the probe module 100 and the puncture module 200 to move in the Z1 direction.

[0083] For the specific implementation manner of the puncture needle unlocking device of the ultrasonic puncture guiding device provided by the present invention, reference may be made to the foregoing description, and details are not described herein again.

[0084] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
